CHARLES T. RIDGELY, OF SPRINGFIELD, OI-IIYO. y

wI E1VIOUNTABLE WHEEL.

To all 'whom it m ay concern.

Be it known that I, CHARLES T. RIDGELY, a citizen of the United States, residing at Springfield, in the county of Clark and Stateof Ohio, have invented certain new and useful Improvements in Demountable 'heels, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to demountable wheels and more particularly to that type of wheel in which the body of the wheel may be removed from the hub without disturbing the latter or exposing the interior or bearing surfaces thereof.

rlhe object of' the invention is to provide a wheel of this kind with means whereby thebody of the wheel may be quickly and easily locked to or released from the hub, and in which this may be accomplished without the use lof tools other than an operating handle.

To. this end it is a further object ofthe invention to provide suoi a wheelwith a plur lity of locking devices ywhich may be simu taneously actuated to move thef'same linto or out of operative position by means ofen actuating device arranged on the outer sideof the wheel.

vide such a"device which will be'very simg/ ple in its construction, comprising but a/L'may these parts of such ,it to be readily7 passed over the hub caple.y

few parts and having Specification of Letters Iatent.

It is also an objectofthe invention to pro\/ Patenten Feb. 29, 191e;

purpose of illustration only, and that the invention is applicable to wheels of various kinds and that the changes necessary to adapt the vsame to the differences in construction of the various wheels may be made without departing` from the spirit of' my l invention. y

As here shown, the wheel as a whole is mounted upon an axle 1 of ordinary construction, and comprises a main hub 2 rotatably mounted on the spindle of the axle,"` preferably provided with anti-friction bear# ings 3and having its outer end vclosed by means of a cap 1. The hub 2 is of a well` known kind and is provided near its inner end withv a radial flange 5 to which, in the original wheel, the spokes were bolted. In applying4 my invention to this wheel I havev removed the body of the wheel from the 'hub 2 Aand have provided the same with a supplemental hub 6 which fits snugly onto the central or body portion of the main hub and is movable axially of said 'main` hub to permit it to be placedV on and re moved from the same. In the present instance, the central portion of the main/hub is enlarged by means of a sleeve 7, which' is rigidly secured thereto and wheninpla'ceforms a part of the main hub. 'Ihis'sleeve is used merely to increase the diameter of the main hub so that the supplemental hub be made of a size which will enable a strong, durable character that they wiIlQIn other types of wheels this sleeve would not be liable to be broken or disarranged, and, further, to provide the device as a whole of 'such a character that it can be manufactured at a comparatively low cost.`

In the accompanying drawings Figure 1 is a sectional view taken centrally through beom'itted, or, in the present type of' wheel if the invention was embodied in the .wheel` when it was originally built the hub would bev thickened without the use of a sleeve, The sleeve 4may be rigidly securedto the, hub in any suitable manner. As here a wheel embodyingmyinvention, showing/shown, it is retainedV in place by means ofa` two-part collar S which 1s mounted upon kthe main hub; Fig. 8 is an eleva-tion of the outer side of the wheel; Fig. 4 is an elevav tion of the inner sideiof the wheel; and

of the hub.

Fig. 5 is a sectional View taken transversely In these drawings I have illustrated one lembodimentof my invention and havev shown the same as applied to one of the the hub between the outer end of the sleeveN and the flanged end of the hub. The supplemental hub comprises two vparts having" radial flanges 9 and `10, between \vhich,.the. spokes 13 are clamped by meansof ,bolts 11. The nuts on the inner end of the bolts:V are arranged in openings in the iiange 5. of the main hub 'to resist any tendency of` the supplemental hub to rotate upon they:

main hub. In the present construction the bolt holes with which the flange 5 was'v originally provided have been enlarged shown at 12, to receive the nuts. Th

when the supplemental hub is plaeedin `position upon the main hub the nuts will en ter the respective openings, as shown in Fig. l1, and will lock the two hubs against relative rotation.

To firmly secure the supplemental hub in position upon the main hub I have provided one of the hubs, in the present instance the supplemental hub, with a plurality of locking devices or dogs which are movable into and out of operative engagement with apart of the other hub, and I have provided a device by means of which these dogs may be simultaneously actuated to move them into or out of their locking positions. In that construction here illustrated the suppleinenl tal hub 6 is provided with a series of axial recesses 1l,.in each of which is mounted a locking member or dog 15 which is pivoted on an axis extending transversely to the hub, as shown at 1G. The main hub has a shou1- der to coperate with each of the locking dogs 15 and this shoulder is' preferably formed by providing the enlarged portion of the supplemental hub with an annular groove 17 arranged near the inner end thereof and in the paths of projections or noses 18 on the locking devices or dogs as they are moved in one direction. It will be obvious that when the projections 'of the lock* ing devices lie in the groove 17 the supple@ mental hub is held against axial movement relative to the main hub. The dogs are of a relatively large colistruction and are mounted snugly between the side walls of the respective recesses, thus reducing the strain on the pivot pins to a minimum and rendering the construction as a whole a very powerful one, and one which is not liable to be injured even by the most severe strains to which 1t may be subiected.

To actuate .the several locking devices simultaneously. I have provided the supplejmental hub with an actuating device which isi-here shown in the form of a collar 19 rotatablv mounted in the outer end of the hub and. preferably screw-threaded therein so that its rotation will impart axial movement thereto. This collar has in its inner end an annular groove Q0 adapted to receive a. projection Aor tail '21 extending outwardlyT from each of the locking devices. This groove hasboth of its side walls inclined, so that the axial movement of the collar `will Y cause one or the other of the inclined walls thereof, depending upon the direction Ioi movement of the collar, to act upon the prof jections or tails 21 of the locking dogs and rock the several dogs about their axes. Rotatory movement may be imparted to the collar in'. any suitable manner, as by means of a Spanner wrench. but I prefer that the actuating device should be permanently secured to the'collar and I have, therefore, rigidly `secured to the collar a device 22 which is similar in construction to a spanner wrench and is adapted to be connected with an actuating handle 23. This actuating handle is preferably detachable from the device Q2 and to this end the latter is slotted, as

lshown at 2l, to receive a stud 25 carried by sary to attach the operating handle 23 toA the actuating device and impart rotatory movement thereto, in practice about two complete rotations are required, and this rotatory movement will `cause the cam groove in the collar to move the dogs into .their inoperative positions, thereby releasing the supplemental hub from the main hub and ]giermitting the foi-iiieahte` be withdrawn. Then the body of the wheel.I either the one that was removed or a substitute therefor, is replaced upon the hub it is moved into engagement with the flange 5,which limits its inward movement, and i'otatory movement is again imparted to the actuating device, thereby moving the dogs into their locking positions and lirmlv securing the supplemental hub in position upon the main hub. The noses of the several dogs snugly engage the forward side wall of the groove 17, and, inasmuch as the supplemental hub bears against the flange 5, of the main hub, it will be apparent that there is no lost motion between the two hubs but that they are rigidly secured one ,to the other. The interlocking connection between the supplemental hub and the main hub. which is provided by the bolts 1,1 andthe holes in the flange 5, eftectually prevents any relative rotatory movement of these parts. Consequently, the construction as a whole is exceedingly rigid and very powerful. The device is very simple in its construction` has a small number of parts, and has these parts of such a character that they can be manufactured at a coinparatively low cost. Further, the deviceis exceedingly simple in its operation. and the operation is of suchva character that it is practically impossible to fail to rigidly connect the two hubs, because the actuating d`evice is movable in one direction only. Further, the device is ot such a character that it can be embodied either in new wheels at the factory or it can be readily built into old wheels, utilizing the original hubs, spokes, rims. etc., and adding thereto the supplemental hub and locking devices.
